Image processing often needs to extract ROI from images, and this article uses Python to extract ROI from images.The module used is PIL (Pillow), an image processing library, the function used for the crop method in the class image.The function prototypes are:Image.crop (box= None) Returns a rectangular region fromThis image. The box isA 4-tuple defining the left, upper, right, andLower pixel coordinate. th

Today, the IT department must perform more business functions, which makes the concept of "black box" technology gradually fade down. That is to say, it is used not only because it is the best in the market or the trend of development,, the current enterprise or organization uses it to meet specific business needs and obtain special business value. It also runs through a series of processes, such: reduce operation costs, develop new products, and expand business opportunities. Currently, enterp

1. Factors affecting the ROI ROI is usually calculated based on the income gained divided by the input cost. If we start a new project, we useTestThe value is divided by the test cost to calculate the ROI of the test. Sometimes,Automated TestingThe introduction takes place after a period of time that the manual test has been completed. The economic cost of automa

Any online advertising system, are faced with the problem of ROI, for Invest, we do not consider, because there are many ways for traffic can be bought back, also can not be optimized (of course, when RTB is optimized). Return is the main optimization direction,return= Ctr * Value created per click. For example: click-through rate is 10%, each Click brings the benefit is 5 yuan, then the profit of each hit is 10% * 5 = 0.5 Yuan.There are two very impo

Test automation is often used as a means of reducing test costs, increasing test coverage and effectiveness, and shortening test cycles. In fact, many software organizations regard automation as a key step in building a mature QA system, and it can be of great value if automated implementation can be implemented effectively. However, automated testing is no substitute for manual testing, and the latter is a vital part of testing software applications in its entirety. Automated testing can lead

, analyze the components, and then combine them. Three major components of VoIP deployment need to be evaluated: the plan itself, infrastructure technical support, and user Technical Support/upgrade. VoIP plan If you don't have any plans to maintain this situation, all your planned costs are equal to $0. Therefore, you need to minimize the labor cost budget. However, it should be noted that the real key issue lies in execution. If you encounter integration troubles and technical difficulties, ma

And, with the time spent on the first project, I can do almost 12 projects like the second one, and you can imagine how much it would do for me. In doing so, I can save money for my clients and improve my own work cost assessment (get more revenue). Investment Reporting (ROI) I think it's very clear now that using Web Standard development can save time and money. I must admit that learn

ROI = average benefit over three years/initial cost The two most important factors to first look when assessing ROI potential are: Breadth-how many people will be helped? If it saves a miniscule amount of time, but is used by everyone in your organization, it might be worth it. Repeatability-How often will people use the application? Obviously you might see a return much sooner by automating daily ta

." The reason why the Aspect participating in the study can maximize Roi is mainly due to the following: · Improve call center efficiency by improving daily work arrangements and personnel utilization. · Provide more interaction opportunities for agents and managers to improve the transparency of customer contact. · Use Automation, integration, reporting, induction training, and other functions to reduce the operation costs of the contact center. · I

To display the ROI of an image, select an area in the image to display the original image of the area. Its core problems are summarized as follows: ①. Obtain the thumbnail image. ②. Implement mouse events and get the coordinates of the mouse 3. Convert the coordinates to the coordinates in the original image, and then find the required original image data area and read it out. 1. thumbnail The key to displaying the original image thumbnail is to find
